All that ever seems to get discussed is winterization/dewaxin. Yawn. Ever stop and think to what you're leaving in the end product?
Wanna "dewax" more thoroughly and remove additional contamination at without loosing so much time to the freezer? read on.
Some undesirable compounds left after dewaxing have hydrophyllic and phobic components in their chemical chain making separation difficult. A hexane/saline wash takes care of this, but this process scares people away with its "chemicals" and additional labglass. Additionally, hex/salt is more suited for "cleaner" starting materials, ie distillate, unless you wanna put 10gal of salt water through a few grams of shit crude.
While i still usually perform some sep funnel work after these processes, it's not necessary to ending up with a great result.
So degumming. There are a few ways of going about removing gums and phosphitides from an extract. I'm only going to cover portions of one way.
So kids if you wanna try something fun at home go to the canning section in the store or amazon and grab some citric acid.
i like to take my "rough crude" nothing more than regular filtered alcohol extract and when its down to a 4:1 volume of alc:extract and still warm from solvent recovery ill dump in a couple hundred ml's of water/citric acid and the separation happens right before your eyes. You can toss it in the freezer at this point for an hour or two to promote further nucleation of shit.
You'll be left with a hell of a pile of soap and some much clearer and cleaner extract to work from.
